HM62W16255HC Series

4M High Speed SRAM (256-kword × 16-bit)

ADE-203-1200D (Z)

Rev. 3.0

Dec. 5, 2002

Description

The HM62W16255HC is a 4-Mbit high speed static RAM organized 256-kword × 16-bit. It has realized high

speed access time by employing CMOS process (6-transistor memory cell) and high speed circuit designing

technology. It is most appropriate for the application which requires high speed, high density memory and

wide bit width configuration, such as cache and buffer memory in system. The HM62W16255HC is

packaged in 400-mil 44-pin SOJ and 400-mil 44-pin plastic TSOPII for high density surface mounting.
